ROOF.

Application filed January 12,1926. Serial No. 80,791.

My invent-ion relates to composition roofing, of the type known as roll roofing, more particularly, and has as its essential object the provision of a roof laid from flexible rolls,

' in which there are nailed lap joints, with complete coverage for all nails.

In detail it is my object to provide roll roofing with a surface finish except for a space at both edges, known as a selvedge, in

the roofing art. At the selvedge the finish is omitted, so that by lapping the selvedges, there will be left a depression between each strip as applied. This strip is then covered with a pasted down narrow strip, which not being required to possess great strength, can be made thin enough to leave a level surface to the whole roof, if this be desired. 'Also the narrow bands can be of different color or nature. 1

There is no added factor of applying a sealing compound'of asphaltic nature'over the joints between stri s, as this is customarily done anyhow, and there is the very decided advantage in that the rolls are reversible, so that when out off diagonally at any angle, at a hip in the roof, the same strip can be turned 180 degrees, and the same angle will be presented for starting the next strip. As is evident, this saves waste in laying roofs, and in many cases this saving is very considerable.

I accomplish the advantages described together with others which will be noted, by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawin Figure 1 is a p l an view of a piece of flexible roofing.

' Figure 2 is a like view of the sealing band.

Figure 3 is a section taken across Figure 1, on line 2, 2.

Figure 4 is a section taken across Figure 2, on line 4, 4. I

Figure 5 is an enlarged section of the covered lap joint.

Figure 6 is a section on a larger scale, showing the method of laying the strips.

The roll roofing which will ordinarily be used by me, will be normally formed of a bod of felt 1, having a mastic coating, the sur ace of which is covered with mineral granules as indicated at 2. The felt body is left free of mastic and granular surfacing at r 3, along each lateral edge, thereby forming a double selvedge for each strip.

The sealing strip is formed preferably of a l ghter gauge felt 4, with a surfacing 5, which is similar to the surfacing 3, but not so thick. The color of the mineral surfacing may be the same as the main roofing strips, or t may be different, and the width of the sealing strip will preferably be the same as the lap oints formed in applying the selvedge of one strip over the selvedge of the adjoinmg strip. It may, however, be wider than the joint, for special effects.

The best way of laying roll roofing is vertlcally of the roof deck. As indicated the strips are laid from left to "right or right to left, with the selvedges 3 overlapping. The nails 5 are driven through the lapped selvedges into the roof deck.

Then an adherent substance, preferably asphaltic in nature, is applied to cover the lapped selvedges, and the small strip is laid with the surfacing 5 on the outside, so as to cover the lapped selvedges, and adhere thereover.

When a hip is reached by a strip it is cut off, at the angle suitable to make a fit, and the roll then turned around and the next course laid, by applying the angularly cut off edge to the hip, where it will fit properly.

The thickness of the sealing strip is not es-' banded effects, or without any substantial showing of the presence of the sealing strips Having thus described my invention, what I claim as new and desire to secure by' Letters Patent, is Y 1. In a roof, the combination of strips having a felt body, and a granular surfacing, said surfacing bein removed at the edges to form selvedges, sai strips laid so as to overlap at the selvedge and nailed to the roof deck through the selvedges, and sealing strips secured over the selvedges, said strips also being formed of a felt body with granular surfacing thereon but having an overall thickness substantially the same as the thickness of the granular surfacing on the felt bodies.

2. In a roof, the combination of strips having a felt body, and a granular surfacing, said surfacing being removed at the edges to form selvedges, said strips laid so as to overlap at the selvedges and nailed to the roof deck through the-selved es, and sealing strips secured over the selve ges, said strips also being formed of a felt body with granular surfacing thereon but having an over all thickness substantially the same as the thickness of the granular surfacing on the felt bodies, said sealing strips being secured over and covering the lapped joints, and being equal to the Width of the joint so formed by said selvedges.

3 In a roof, the combination of strips having a felt body, and a granular surfacing,

said surfacing being removed at the edges to form selvedges, said strips laid so as to overlap at the selvedges and nailed to the roof,

, deck through the selvedges, and sealing strips secured over the selved es, said strips also being formed of a felt body with granular surfacing thereon but having an over all '20 strips having a granular surfaced outer face,

and having selvedges of reduced thickness, said strips laid so as to overlap at the selvedges, and means securing the selvedges of said strips to the roof deck, and joint strips to cover the selvedges also having a granular outer surface, said strips being narrower than the first mentioned strips and of reduced thickness so as to form a uniform plane surface of the roof;
